KORATHERM HORIZONTAL - M

Design radiators with horizontally aligned profiles and bottom middle connection

Unobtrusive luxury with a unique combination of elegance and heat output - this is KORATHERM HORIZONTAL-M. It is a suitable solution for heating rooms with large-space glass surfaces such as shop-windows, reception rooms, open plan living areas, larger rooms with high ceilings, panoramic windows, halls, etc.

It is designed for double-pipe pressurized heating systems, the heating profiles are aligned horizontally. The connection to the heating system is always bottom middle with the connecting pitch of 50 mm (example of product code K11HM). It is equipped with 2 bottom connections with inside thread G½, an air vent and a blanking plug with G¼ thread. All types are delivered with a top grill.

We recommend to use the Connection fittings HM (pdf, 3 MB) for radiators with bottom middle connection.

KORADO now offers also towel hangers and pegs which extend the practical use of KORATHERM design radiators.
